In the garage, after Lady Heather hands Grissom the bag with the condom in it, Grissom's hands on the bag and the bag both change positions in between shots.
Sparks, Nevada is 335 miles away from Las Vegas, Nevada. It would take Grissom over 7 hours to drive there, and it wouldn't be under Vegas jurisdiction.
Grissom tells Lady Heather her daughter was found near Sparks. Sparks is near Reno, not Las Vegas.
